Android检测网络类型

主要使用BroadcastReceiver去监听网络变化，实时发广播去通知：

首先要封装一个工具类去检测网络

public class NetWorkUtils {
 private static final int NETWORK_TYPE_UNAVAILABLE = -1;
    // private static final int NETWORK_TYPE_MOBILE = -100;
    private static final int NETWORK_TYPE_WIFI = -101;

    private static final int NETWORK_CLASS_WIFI = -101;
    private static final int NETWORK_CLASS_UNAVAILABLE = -1;
    /** Unknown network class. */
    private static final int NETWORK_CLASS_UNKNOWN = 0;
    /** Class of broadly defined "2G" networks. */
    private static final int NETWORK_CLASS_2_G = 1;
    /** Class of broadly defined "3G" networks. */
    private static final int NETWORK_CLASS_3_G = 2;
    /** Class of broadly defined "4G" networks. */
    private static final int NETWORK_CLASS_4_G = 3;


    // 适配低版本手机
    /** Network type is unknown */
    public static final int NETWORK_TYPE_UNKNOWN = 0;
    /** Current network is GPRS */
    public static final int NETWORK_TYPE_GPRS = 1;
    /** Current network is EDGE */
    public static final int NETWORK_TYPE_EDGE = 2;
    /** Current network is UMTS */
    public static final int NETWORK_TYPE_UMTS = 3;
    /** Current network is CDMA: Either IS95A or IS95B */
    public static final int NETWORK_TYPE_CDMA = 4;
    /** Current network is EVDO revision 0 */
    public static final int NETWORK_TYPE_EVDO_0 = 5;
    /** Current network is EVDO revision A */
    public static final int NETWORK_TYPE_EVDO_A = 6;
    /** Current network is 1xRTT */
    public static final int NETWORK_TYPE_1xRTT = 7;
    /** Current network is HSDPA */
    public static final int NETWORK_TYPE_HSDPA = 8;
    /** Current network is HSUPA */
    public static final int NETWORK_TYPE_HSUPA = 9;
    /** Current network is HSPA */
    public static final int NETWORK_TYPE_HSPA = 10;
    /** Current network is iDen */
    public static final int NETWORK_TYPE_IDEN = 11;
    /** Current network is EVDO revision B */
    public static final int NETWORK_TYPE_EVDO_B = 12;
    /** Current network is LTE */
    public static final int NETWORK_TYPE_LTE = 13;
    /** Current network is eHRPD */
    public static final int NETWORK_TYPE_EHRPD = 14;
    /** Current network is HSPA+ */
    public static final int NETWORK_TYPE_HSPAP = 15;

    /**

        }

}

新建一个BroadcastReceiver去实时监听网络状态变化

public class NetWorkStatusReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(ConnectivityManager.CONNECTIVITY_ACTION)) {

            String operator = NetWorkUtils.getProvider(context);
            String netType = NetWorkUtils.getCurrentNetworkType(context);

            Toast.makeText(context, "运营商："+operator+"\n 网络状态："+netType, Toast.LENGTH_LONG).show();
        }
    }
}
